solder other metals to copper?

Solder, say, steel u-bolts to copper pipe? Same procedure, clean 'em up,
flux 'em, heat 'em up and apply solder?

Your best bet would be to get the correct brazing rod from a supply
house. The U bolt may have a zinc coating and it may have to be removed
in order to braze the steel to the copper. I have special brazing rods
from the supply house to braze steel service valves to copper pipe that
I use for refrigeration work. Tell the guys at the supply house what
you're trying to do and they can tell you what you need. Of course, you
can always experiment.
